APPARATUS FOR FILLING AND SEALING RECEPTAGLES.

Application filed July 9, 1921. Serial No. 483,443.

To all whom, it may concern:

Be it known that I, IRVING STANLEY, a citizen of the United States, and a resident of the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improved Apparatus for Filling and Sealing Receptacles, of which the following is a specification.

This invention relates to apparatus for filling and sealing containers or receptacles made of paper, such as parafline aper, sa1d receptacles havin an open end W ich is collapsed and inc ed together to close the same and sea ed by securin the end in collapsed condition, and it is the principal object of the invention to provide in apparatus of this character receptacle filling means, means to deliver the receptacles from the filling means to a conveyer to support and position the receptacles relativeto collapsing and sealing means, and to deliver the filled and sealed receptacles from the conveyer, and to provide apparatus-for this purpose which is automatic and efficient in operation. a

It is a further object-of the invention to provide an improved receptacle carrying conveyer in apparatus of this character, and

to means to support a receptacle during the operation of co lapsing and sealing of the receptacle to relieve the conveyer of any strains and stresses during the operation of closing and sealing of the receptacle.

It is another object of the lnvention to provide an improved means to collapse the ope-n end of the receptacles to close the same, and provide improved meansfor arranging a metallic sealing strip with prongs to engage the material of the collapsed end of a receptacle, and to apply the pron ed strip to the collapsed end of the receptac e to seal the same.

It is another object of the invention to rovide improved'means to automatically deliver receptacles from theconveyer after a predetermined number of receptacles have been closed and sealed.

Other objects and advantages will hereinafter appear. 7

Similar characters of reference designate like parts throughout the different views of dered material or 11 uid, shown in the present instance as consisting of liquid, such as milk, and then to seal the receptacles, the receptacles being made of paper, such as parafiinepaper, consisting of a sheet rolled to tubular form, preferably of truncated conical form with one end, preferably the end -of greatest diameter, provided with a closure and the opposite end open and constituting the mouth of the receptacle. A series of such receptacles R, shown as six in number, are placed upon ment with circular portions of members or abutments 14 fixed in spaced relation upon a slide 15 mounted at opposite ends upon guides 16, the receptacles being positioned in alinement with the outlet of measuring means; (designated in a general way by 17) constituting a part of receptacle filling means to deliver a predetermined quantity of material to the receptacle.

The receptacle filling means comprises a tank 18, having a removable cover 19, to

which the material is delivered from a suitable source of supply by a pipe 20 having an outlet leading into the tank, the delivery of the material to the tank being controlled through the pipe by a float controlled valve as shown in a general way at 21. The material is delivered from the tank to the receptacle by dippers 22 (Figure 10) open at the top and normally engaging in cups 23 secured to and projecting downwardly from the, bottom of the tank; said cups being arranged with nipples or nozzles 24 carried b tubes 25 extending up centrally throug the cups and constituting a continuation of the nipple orifice, said tubes being 0 en at the upper end and upon which the dippers are slidably mounted. The dipper carrying cups are so arranged that when the dippers engage therein the open end of the dip ers' will be substantially flush or slightly elow the bottom of the tank to permit of the flow of the liquid from the tank into the dippers, and to discharge the 11 uid from the dippers they are raised or lifte to cause the liquid to flow from the dippers through the upper end of the tube 25, and after the liquid has been discharged from the dippers they are again lowered into the cups to receive a further supply of liquid.

To raise and lower the dippers they are connected by rods 26 to a crank shaft 27 (Figure 2) journalled in the opposite side walls of the tank and rotated by a crank arm 28 fixed to a projecting end on the shaft, said crank arm being actuated by a cam 29 on a shaft 30 and operatively connected to the cam by a link 31. The shaft 30 is driven from a shaft 32 through a pinion 33 (Figures 1 and 2) on said shaft meshing with a gear 34 on a countershaft 35, and pinion 36 on said latter shaftmeshing with a pinion 37 on shaft 30. The shaft 32 is driven from a suitable source of power, shown as an electric motor M having a worm fixed to the shaft thereof meshing with a worm wheel 38 loose on the shaft 32 and opthe table in alineeratively connected to the shaft through a clutch, one member 39 of the clutch being integral with the worm wheel and the other member 40 mounted on the shaft 32 to 1'0- tate therewith and have sliding movement thereon, said clutch member 40 being thrown into and out of operative connection with the clutch member 39 by the bifurcated end of an arm 41 engaging an annular groove in the clutch member 40, said arm being fixed to a slidably supported actuating rod 42.

The receptacles are, after being filled, transfered from the table or receptacle support to a conveyer to be transported to means to collapse and seal the open end of the receptacles. This conveyer comprises a pair of sprocket chains 43 passing in parallel and spaced relation around sprocket wheels 44, 45 fixed to shafts 46,47 journalled in hangers fixed to the end supporting standards S of the frame-work. Receptacle supporting sides in the form of plates 48 are successively arranged upon the chains to extend transversely thereof and are pivotally connected to the pivot pins of the chain links, said plates having upwardly turned flanges 49 at the leading and trailing ends and a central perforation 50 for a purpose to be hereinafter described. The conveyer is intermittently advanced predetermined distances b a ratchet wheel 51 fixed to shaft 47 with w ich a ratchet pawl 52 pivotally carried by an arm 53 hung on theshaft 47 co-operates. The pawl is actuated by a cam 54 on shaft 32 through a pivoted lever 55 carrying a roller at one end to co-operate withthe cam 54, the other end being con ngcted to the pawl carying arm 53 by, a link 5 The receptacles are delivered from the table or receptacle support to the receptacle seats 48 on the conveyer by the movement of the slide 15, this slide being reciprocated by a pair of arms 58 fixed to a rock shaft 59 (Figure 3) the arms having bifurcated ends for the engagement of fingers 6O fixed to and extending laterally from the slide. Rocker arms 58 are actuated by a cam 61 on the shaft 30 through a link 62 pivotally connected to one of the arms and carrying a roller to co-operate with the cam.

The ratio of rotation between the shaft 32 and the shaft 30is six to one whereby six intermittent movements will be imparted to the conveyor to one receptacle transferring movementof the slide 15, and the dippers of the receptacle filling means, the movement of the dippers being alternate with the movement of the receptacle transferring slide. By this arrangement six intermittent movements will be imparted to the conveyer whereby six receptacle receiving seats of the conveyer will be positioned relative to the receptacle supported in relation to the receptacle filling means permitting of a sufiicient lapse of time for the replenishing of the receptacles to the receptacle filling means and without any interruption in the actuation of the conveyer.

The receptacles are successively positioned by the conveyer relative to receptacle collapsing and sealing means mounted upon the table or bed B in juxtaposed relation to the receptacle filling means and above the receptacles on the conveyer. The receptacle collapsing means comprises a pair of heads or slides 64, 65 slidably mounted in a slideway 66 mounted upon or integral with a fixture 67 (Figure 6) mounted upon the table or'bed B. The slides or hcadsare normally maintained in opposed and spaced relation as shown in Figure 2, and the receptacles are positioned with the open end between said heads during the periods of rest of the conveyer. For this purpose a plunger 68 is carried by a bracket 69 (Figure 4) fixed to the frame work.to extend downwardly and forwardly between the stretches of one of the conveyer chains with the plunger located in the space between the chains of the conveyer to have vertical sliding movement in the bracket and relative to are actuated from a cam 81 on shaft which plunger the perforations in the receptacle supporting plates of the conveyer are adapted to be alined to permit of the movement of the plunger through said perforations to engage the bottom of a receptacle supported upon a receptacle seat and to lift it from the conveyer to position the open end of the receptacle between the collapsing heads or slides.- After the open ends of the receptacles have been collapsed and sealed the plunger is receded to seat the receptacle upon a receptacle seat of the conveyer. To reciprocate the plunger pins extending from opposite sides of the plunger slidably engage in slots in the plunger support and in bifurcations at the ends of arms 70, as shown at 71, Figure 4. To reciprocate the plunger the arms are fixed to and project forward from a rock shaft 72, said shaft being rocked by a cam 73 on shaft 32 through a link 74 carrying a roller to co-operate with the cam and connected to an arm 75 on the shaft 72.

To reciprocate the collapsing slides 64, 65, arms 76, 77 pivotally supported upon the bracket 67 have bifurcated ends for the en gagement of pins projecting upward from the slides, as shown at 78, 7 9, the arms being connected by a link 80 in such a manner that as one of the levers is moved to move one slide in one direction the other slide will be operated in opposed relation. The slides a link 82 carrying a cam following roller and connected to an arm 83 fixed to the pivotal support of the arm '76. The cam 81 operates to reciprocate the slides toward and away from each other and after the slides have been moved away from each other the plunger 68 is actuated to again reseat. the receptacle upon the receptacle support of the conveyer.- To maintain the receptacle in position'between the collapsing slides during the collapsing movement thereof a guide or gauge is provided to engage at opposite sides of the receptacle. This gauge comprises a supplemental slide 84 slidably carried below the slide member 65 and normally urged by a spring 86 in a direction to extend beyond the receptacle collapsing face of said head with said end of the supplemental slide bifurcated to provide the gauge fingers 85, as shown in Figure 8.

Simultaneously with the collapsing movement of the heads 64, 65, the clamping strip 87 arranged with prongs stamped therefrom is applied to the collapsed end with the prongs of the strip piercing the material of the closure and upset thereby sealing and retaining the collapsed end of the receptaclein collapsed condition. This strip is inter-' mittently fed in interposed relation to the collapsing heads from a roll 88 (Figure 1) with a portion of the strip engaging a seat extending forward of the head 64 as shown in Figure 8. This seat is formed by a supplemental slide 89 slidably carried below the head 64 and normally urged to extend a pre determined distance beyond the receptacle collapsing face of said head by a spring 90.

mechanism comprising ablade 91 slidably carried by the head 65 and normally urged outward from said head, said blade co-operating with a cutter member 92 carried by the head 64. I

To intermittently feed. the strip to, the collapsing heads 64, 65 a pair of positively driven-feeding rollers 93, 94 rotatably carried by the bracket 67 are provided. The wheel 94 is arranged with-peripheral grooves for the passage of the prongs of, the sealing strip. The feeding wheels are intermittently rotated by pawl and ratchet mechanism comprising a ratchet wheel 95 fixed to a stud shaft 96 in the fixture 67 and a cooperating pawl 97 pivotally carried by an arm 98 hung on the shaft 96, the pawl carrying arm being actuated by a cam 99 on shaft 32 operatively connected to the arm by a link 100. arranged with a cam follower. The movement of the ratchet wheel is trans- -mitted to the feed wheels through a gear &

collapsing heads 64:, 65 are moved and 9, the cutter 91 is actuated to sever the and die mechanism comprises sealing strip by a cam 103 on shaft 32 through a cam follower carrying rod 104 pivotally connected to an arm 105 fixed to a shaft 106 rotatably mounted in the bracket 67 (Figure 6), said shaft carrying a second arm 107 having a bifurcated end to engage pins projecting from the cutter, as shown at 108-.

Alternately with the feeding of the clamping or sealing strip 87 the strip is provided with sealing prongs by punch and die mechanism interposed between feeding wheels 93, 94 and the strip roll 88, as shown in a general way at 109 in Figure 1. This punch adie member 110 fixed i'n'fla recess portion of a fixture 111 fixed to the bed B, said die member having a longitudinal recess of two widths with the portion of less width at-the bottom and havmg a series of alined and spaced pins 113 fixed therein and a perforated plate 114 arranged in the portionv of greatest width in superposed relation to the pins, the perforations in said plate being positioned in line with the spaces between the pins with the portion of the recess of reduced width form-.

ing a seat-for saidplate. Plates 115 are fixed to the outer side ofthe die member to overhan the recess form'inggibs to retain and gui e the clamping strip between said plates and the perforated plate 114. A punch consisting of a head 116 is slidably mounted in the recess of the fixture 111 in opposed relation to the die member 110 and to have movement toward and away from said member, said head carrying a series of alined punches 117 in alinement with the perforations in the die plate 114, a perforated stripping plate 118 being carried by the punch with the perforations in register with the punches and normally urged outward toward the ends of the pins by'springs 119. The unch is reciprocated through a lever 120 Figure 1) pivotally supported upon the die fixture and carrying a roller to co-operate with a cam 121 on the shaft 32, the lever being connected to the punch head by a plunger 122.

The receptacles after beingsealed and returned to the conveyer are positioned by the intermittent movement of the conveyer relative to means to deliver or eject the sealed receptacles fromv the conveyer to a tray T which may be removably supported upon a shelf 123 carried by the frame-work. This delivery means comprises a slide 124 slidably supported at opposite ends by guide receptacles on the conveyer.

.eratively connected to the members 125 fixed upon te bed B, abutments 126 being fixed upon said slide and having a rounded portion for the engagement of the The slide is reciprocated transversely of the movement d of the conveyer by a rock shaft 127' rotatably mounted at one end in the end standard S and at the opposite end in a hanger 128 fixed to the bottom of the bed B, said shaft being connected to theslide by arms 129 fixed to said shaft having bifurcated ends in which engage fingers 130 fixed to and extending laterally from the slide. The shaft 127 is rocked by a cam 131 on shaft 30 opshaft by a rod 132 pivotally connected to an arm 133 of the rock shaft. The receptacle delivery slide is operable during a period of rest of the conveyer, and the operation of the slide is timed to have one movement imparted thereto to six intermittent movements of the conveyer whereby as the delivery slide is actuated six in alinement with the abutments 126 on the delivery slide to be engaged by said abutments as the slide is actuated.
